problem with do not duplicate

Goal show table with 3 posts from cat:AccordionPg1 on row 1 and next 3 post on row 2. Before I added the do not duplicate code I had it right except second row contained the same three posts as the first. Now I only get one row of three posts. Sorry site not on internet.

<?php
/*
Template Name: nosidebar3

 ?>
<?php // Do not delete these lines ?>
<?php 	/* get all options: */
# error_reporting(-1);
include (TEMPLATEPATH . '/functions/bfa_get_options.php');
global $bfa_ata;

$left_col2 = "off";
$left_col ="off";
$right_col2 = "off";
$right_col = "off";

get_header(); ?>
